There is provided a preview distribution technique capable of realizing a flexible preview distribution between a distribution side and a user side. According to the technique, preview meta data describing reference destination information to the preview-constituting data of a plurality of types constituting the content preview is transmitted to a reception terminal. The reception terminal acquires the preview-constituting data by using the reference destination information described in the preview meta data and generates/reproduces the preview. Thus, when modifying the preview, the reception terminal can reproduce the preview after the modification, by acquiring only the data constituting the preview of the modified part, thereby easily modifying the data constituting the preview. That is, it is possible to perform a flexible preview distribution.
